1Heat oven to 375°F. Place tortillas (from dinner kit) on large cookie sheet. Spray both sides of tortillas with cooking spray. Bake 5 to 6 minutes, turning once, until lightly browned around edges.
2Meanwhile, in 2-quart saucepan, mix chicken and black beans. Stir in seasoning mix and two-thirds of the enchilada sauce (from dinner kit). Cook over medium-low heat about 5 minutes, stirring occasionally, until hot.
3On each tortilla, spread 1/3 cup chicken mixture; top with scant tablespoon of remaining enchilada sauce. Sprinkle with cheese and tomato. Garnish with fresh cilantro leaves. Serve immediately.
